摘要

通过对江西省贵溪市典型重金属污染退化红壤(菜园土)进行盆栽试验显示

施用石灰

特别是施用高量石灰

将土壤pH值调至微碱性

可以显著提高植物的净光合速率

增加土壤微生物量C(其中又以纤维分解菌的变化最为显著);降低土壤有效态重金属的含量

减轻重金属对植物的危害

是现有条件下切实可行的改良措施。

Abstract

Pot experiment on red soil(garden soil) contaminated by heavy metal in Guixi city

Jiangxi province was conducted.The results indicated that using lime to tune soil pH to lightly alkalescence could improve net photosynthesis significantly

increase soil microbe C (especially for cellulose-decomposing bacterium)

reduce the available content of heavy metal and reduce the harm to plants

so it's the viable amended measurment under the condition in existence.
